In this work, we propose a measurement plane for Software Defined Networking (SDN) architectures for monitoring the network performance and supporting the orchestrator in managing the optical link resources. Concerning the measurement plane, we consider two models that we adopted in other contests: Misurainternet and mPlane. However, due to better scalability, the tests reported in this paper refer to mPlane that has been used in a SDN environment based on Fiber to the X (FTTX) accesses, with procedures of the central unit (orchestrator) that automatically manages GbE links in a regional network. The choices of the orchestrator are based on information received by a reasoner that analyzes the network performance elaborating data detected by active and passive probes. The mPlane-SDN architecture is tested in field measurements concerning FTTX accesses and in Lab to verify the resource allocations in case of traffic congestion. Furthermore, we also show the potentiality of our architecture to evolve toward a distributed controller approach with important advantages for telecom operator strategies.

在这项工作中，我们为软件定义网络（SDN）架构提出了一个测量平面，用于监视网络性能并支持协调器管理光链路资源。关于测量平面，我们考虑在其他竞赛中采用的两个模型：Misurainternet和mPlane。但是，由于具有更好的可扩展性，本文中报告的测试涉及已在基于光纤到X（FTTX）访问的SDN环境中使用的mPlane，其中央单元（协调器）的过程可自动管理GbE链路。区域网络。协调器的选择基于推理机接收的信息，该推理机分析网络性能，详细阐述由主动和被动探测器检测到的数据。mPlane-SDN架构已在有关FTTX访问的现场测量中进行了测试，并在实验室中进行了测试，以在流量拥塞的情况下验证资源分配。此外，我们还展示了我们的体系结构向分布式控制器方法发展的潜力，这对电信运营商策略具有重要优势。
